IndieAppCircle

Sonn

Sonn is a one-line terminal install that adds a persistent reasoning layer to Claude Code. It automatically captures project context, decisions, and boundaries across sessions — then reasons over that history before the agent acts, steering it away from mistakes it was about to repeat rather than retrieving notes after the fact. Everything is local-first: code and memory stay on the developer's machine, and generation runs through their own model credentials.

About Sonn

Is Sonn legit?

Sonn was listed on IndieAppCircle in July 2026 by Aleksandar, who opened it to independent testers. 1 independent tester has used it since and had their feedback accepted by the maker. It is distributed through its own website at sonn.dev. IndieAppCircle is a peer feedback exchange, not a paid-review site: testers earn credits only for feedback the maker accepts, and nobody is paid to be positive. We record what happened here; we do not vouch for a product's business practices.

What platforms does Sonn run on?

Sonn runs on macOS, Windows and other platforms. The maker built it for developers.

Is Sonn still looking for testers?

It is not in the feed right now — the listing is paused until the maker is active on IndieAppCircle again. You can still test it from this page for 5 credits per approved test; the maker is notified when feedback arrives, and feedback left unanswered for 48 hours is approved automatically.

How do testers review Sonn on IndieAppCircle?

Testers are other indie developers. They open Sonn, follow the maker's test instructions, and write up first impressions, confusing moments and bugs. The maker reads each write-up and either approves it — which pays the tester — or rejects it. Only approved feedback is counted on this page. There are no star ratings and IndieAppCircle pays nobody to review anything; it is a feedback exchange, not a review site.
